यहा x = { t ∈ z} है इसलिए

प्रदेश गण Df = x = t = {-3, -2, -1, 0, 1, 2, 3}

सहप्रदेश y = {a / a ∈ N 1 ≤ a ≤ 20}

K(t) = t2 + 2 के लिए t = -3, -2, -1, 0, 1, 2, 3 रखने पर

K(-3) = (-3)2 + 2
= 9 + 1
= 11

K(3) = (3)2 + 2
= 9 + 2
= 11

K(-2) = (-2)2 + 2
= 4 + 2
= 6

K(2) = (2)2 + 2
= 4 + 2
= 6

K(-1) = (-1)2 + 2
= 1 + 2
= 3

K(1) = (1)2 + 2
= 1 + 2
= 3

K(0) = 02 + 2
= 2

t = -3, -2, -1, 0, 1, 2, 3 के लिए विधेय का मूल्य 11, 6, 3, 0, 3, 6, 11 प्राप्त होते है ।
इसलिए प्रदेश समूच्य की दो भिन्न किंमत {-3, 3}, {-2, 2} और (-1, 1) के लिए प्रतिबिंब समान प्राप्त है इसलिए अनेक एक फलन है ।
